squawk out:

D.L Logo was supplied on bootable OS9 version 1.00.00 disk.  Not
bootable on a Coco 3.

64k Coco
One disk drive
A color television
The D.L Logo diskette

To use all the functions, add:
Another disk drive
A multi-pak interface
Speech/Sound cart
Two joysticks
Printer.  Suggested: DMP410 or the CGP-220

Runs off Drive 0.
Manual shows to run Logo
Boot into OS9, at the prompt: LOGO <return>
To run the demo, in Logo: LOAD "DEMO <return>
Once the blue cursor returns: DEMO <return>
If the Speech/Sound cart is installed, it'll talk.
To stop the program hit <break>

As I recall, the demo worked fine on my Coco 2.

Looking through the manual, it doesn't mention anything about
increasing it's memory usage.
